Most Finns belong to the Evangelical-Lutheran Church while a fraction of them belong to the Orthodox Church. The Evangelical-Lutheran Church accepts the ordination of women as priests.

As far as religion is concerned, there are very few dangers for visitors to Finland, even on subjects that in other cultures might be particularly sensitive. Most Finns belong formally to the Evangelical-Lutheran Church (about 75%), while 1.1% belong to the Finnish Orthodox Church; but people in general are fairly secular in their views. Despite this, the Church and its ministers are held in high esteem, and personal religious views are respected. It is difficult to observe differences between believers and everyone else in everyday life, except perhaps that the former lead more abstemious lives.

The number of immigrants in Finland is growing, and increasing contacts with other religions in recent years have increased the Finns' knowledge of them, although there is still much to be desired in their tolerance for people with different religions and cultures.

In addition to the Lutheran, Orthodox, and Roman Catholic churches, there are also Mormon, Baptist, Jehovah’s Witness, Religious Society of Friends (Quakers), Jewish, Muslim and other religious communities, as well as interdenominational English-language church congregations in many university cities and some smaller towns. Host-institution orientations normally mention local religious services in English in communities where they exist.
